Tired of wondering whether the dice are rigged? Before every match the game creates a secret key that decides every roll and shows you its fingerprint, the Dice Seal. When the match ends the key is revealed and the Verify screen rebuilds every roll from it, so you can see that nothing changed during play. The computer never sees future rolls. Play the computer at four levels or a friend on the same phone, with Turkish tavla or international rules, on hand-rendered wooden boards. Works fully offline, no account needed. Free to play with ads between matches; a one-time purchase removes them.

FAQ
How can I be sure the dice are fair?
The seal is shown before the first roll and cannot match a different key. When the match ends, open Verify: it rebuilds every roll from the revealed key and checks it against the seal. The method is written on that screen, so you can repeat it with any SHA-256 tool.
